Abstract

Nowadays, energy consumption has increased as a population increases with socio�economic developments and improved living standards. Therefore, it is necessary to find a
replacement for fossil energy with renewable energy sources, and the potential to develop is
biofuels. Bio-oil, water phase, gas, and char products will be produced by utilizing Spirulina
platensis (SPR) microalgae extraction residue as pyrolysis raw material. The purpose of this study
is to characterize pyrolysis products and bio-oil analysis with GC-MS. Quality fuel is good if O/C is
low, H/C is high, HHV is high, and oxygenate compounds are low, but aliphatic and aromatic are
high. Pyrolysis was carried out at a temperature of 300-600o
C with a feed of 50 grams in
atmospheric conditions with a heating rate of 5-35°C/min, the equipment used was a fixed-bed
reactor. The higher the pyrolysis temperature, the higher the bio-oil yield will be to an optimum
temperature, then lower. The optimum temperature of pyrolysis is 550ºC with a bio-oil yield of
23.99 wt%. The higher the pyrolysis temperature, the higher the H/C, the lower O/C. The optimum
condition was reached at a temperature of 500ºC with the values of H/C, and O/C is 1.17 and 0.47.
With an increase in temperature of 300-600ºC, HHV increased from 11.64 MJ/kg to 20.63 MJ/kg,
the oxygenate compound decreased from 85.26 to 37.55 wt%. Aliphatics and aromatics increased,
respectively, from 5.76 to 36.72 wt% and 1.67 to 6.67 wt%.
